SIGMUND FlSQ-IER, OF PROVDENGE, RHODE ISLAND.

CHAJN CONNECTER.

Application filed February 12, 1924i- Seral No. 6925246.

Be it known that L SIGMUND Fisorlnr.. a citizen ot the United States7residing at lhovideuce, in thel county ot- Providence and State olRhodelsland, have inventedv certainnew and useful Improvements in ChainConnecters, et which the following a specification.

This invention-relates to a connecter -for rele-asably attachingtogether the ends ot a chain* and the like; and the object of thisinvention is to provide such a connecter which consists otf `cooperatingstud and socket members, each having an eye portion adapted to beattached to an end element ot the bhain tor connecting these endstogether.

t 'further object o'f this invention is the provision ot a connectercomprising stud and socket members adapted to be snapped together, eachmember having an eye portion having their attaching parts in sub.-stantially the same plane, whereby oppositely directed strains on thechain ends will not tend to tip the connecter members out of a planesubstantially parallel to that ot' the chain.

TWith these and other objects in View', the

invention consists of certain novel 'features' olf-construction, as willbe more fully described, and particular-l)r pointed out in the appendedclaims.

'ln the accompanyingl drawings:

Figure 1 is an edge view showing my stud and socket connecterl membersas attached to each other and the links ofthe opposite ends ot thechain'connected to the opposite ends ot this connecter.

Figure 2 is a detail of one of the plate members as provided with anattaching eye.

Figure 3 is an edge View showing the attaching eye portion as offset atan angle to the plane oi the plate.

Figure 4l is a sectional side elevation of theJ stud member showing theplate with its eve-member attached thereto.

i Figure 5 is a front View of this stud member showing the eye-memberasextending through the side Wall of .the saine.

Figure 6 is a. sectional edge View showing the socket member with thespring mounted therein also with the plate member mounted therein andhaving an eye-member extending from the edge thereof.

Figure 7 is an edge View showing the eyenieinber as extending throughthe sidewall ofthefsocket plate. I

Figure 8 is atop View or"- the' eye/plate as disconnected fromthe'socket plate.

Figure 9 is an enlarged sectional elevation showing the studmember as.connected to the socket member.

Figure 10 is a View showing an eye member asv providedV with T-shapedhead adapted to be secured to either of the stud or socket members. v

Fig. 11 is a. sectional plan View of the socket member. It is foundr inpractice oiiadvantage, to provide a connecter for' the ends oi' chainsvespeciallyY those Worn for personal adornnient3 and in such a connecterto provide stud and socket members-adapted to be snapped together.- Thegeneral shape of these members may be suoli as to contorni to thegeneral shape'ot the links oit the chain and to lie flat similarly tothe other Vlinks of the chain; also'it is found desirable to provideeye-members which may preferably extend in opposite directions and bedisposed in substantially the same plane so that a strain in oppositedirections on the chain will not tip the connecter out of its normalplane or a plane which lmay be substantially that ot the rest ot'thelinks; also by providing a connecter of this character, the ends otthe chain are securely connected together and may also be readilyseparated when desired;

and the following is a detailed description i loit one construction otconnecter by which these advantageous results may be accompl1shed:

lVith reference to the drawings, 1U

designates the stud member of the connecter, which is preferably formedWith a back plate 11 having a stud orprojecting portion 12 formed fromthe plate, and this plate being herein shown as having upturned 'edgewalls 13 which I have shown as -retaining a second plate 14.

This second plate 14 ris provided with a laterally extending eye portionor tongue 15 which projects throughy an opening 16 in the upturned edgeWall ot the bottom plate, and this eye-member is herein shown as beingturned downwardly at substan` tially a. right angle to the plane of thetace of its plate and then its end 17 is turned off at a right angle andis provided with link /l-l of the chain end thereto.

The socket member oi" this connecter is constructed of a plate 19 havinga central recess or pocketO formed in it, the side ,Walls 2l of thispocket being cutaway to permit the clamping spring 22 to lentendtherethrough .to grip and yieldingly retain the head of the stud l2 whenpressed thereinto. Y

`This plate 19 is provided `with an out-- wardly-turned annular flange23 and a back pla-te 24 is inserted Within this flange and secured inposition by turning the edge of the flange thereover. This back plate isprovided with an eye-tongue 26 having an opening 2T therein and thistongue extends Vthrough a corresponding opening Q8 in the ange. Wall ofthe plate 19" and a ring 2f) may be passed through the tongue opening 27to connect the end link 30 of the chair.

to this eyeineinber. l

In sonic instances instead of providing aV plate 24: to cover the backof the socket meniber, l may torni an eve-member, as illustrated inFigure 10, with the T-shaped head 31 and a shank 32 having an eye 33through lwhich the ring 29 may extend to attach the bracelet link 8Othereto.

I have shown and'desoribed an eye-inember as attached to a. plate whichis secured in position by the walls of the stud and socket plates butthese eye-members may be connected to the respective members oi' theconnecter by any suitable means to eX- tend outwardly `therefrom inopposite directionsito serve as a convenient means for attaching theopposite-'ends ot the chain to the opposite end ofthe connecter.

The foregoing` description is directed .solely towards the constructionillustrated,

buty I desire it to'be understood that rel servel thefprivilege ofresorting to all the mechanical changes to which the Vdevice issusceptible, the invention being defined and limited only by the vtermsof the appended claims.

l claim:

l. A. chain connecter comprising a Socke.' i'nember having a studgripping spring:l mounted therein. a stud member superinoposed upon thesocket member and having an enlarged head portion to snap through` saidspring into the socket portion beyond said spring, said stud and socketmeinbeisI having oppositely-disposed late-rally extend ing attaching eyemembers both disposed iii a plane substantially at the center of thienlargement of said head portion of the stud.

A chain connecter comprising cooperating stiid and socket membersadapted to be separably connected together, each ot said members havinga plate With edge Walls, a second plate secured in each mein ber by saidedge Walls, and an eyc portion iioiii'ied on the edge ot each of 'saidplates to which links of opposite ends of the chain may be connected.

3. A chain connecter comprising ci operating stud and socket ineinbersadapter?` to be separably connected together, each oi" said ineii'ibershaving a plate with edge Wall, a second plate secured in each oi' saidmembers by said edge Wall, an eye on each ot said second platesextending through said edge Wall into position to be engaged bv theopposite ends or" the chain.

d. A chain connecter comprising cooperating stud and socket membersadapted to be separably connected together, each oi said members havinga plate With an edge Wall. a second plate secured in each of saidineinbers by said edge Wall, an eye on each ot said Vsecond platesextending through said edgeavaila one ot said eyes boing offset Vfromthe plane of said second plate and disposed in substantiallylv the planeof the eye on tlie'opposite member.
